Anthropic launches faster and cheaper claude haiku 5.5 model

Anthropic has launched the Claude Haiku 5.5 model, claiming it to be the fastest, most cost-effective, and most powerful version of its Haiku series. The model reduces operational costs by approximately 75% compared to Haiku 4.5. For requests under 100,000 tokens, the input cost is $0.10 per million tokens (about 0.67 CNY), and the output cost is $0.50 per million tokens (about 3.4 CNY). Beyond 100,000 tokens, the input and output costs increase to $0.50 and $2.50 per million tokens, respectively (about 3.4 CNY and 16.8 CNY). Anthropic also reduced the cache retrieval price for Sonnet 5.5 from $0.20 to $0.10 per million tokens (about 1.3 CNY to 0.67 CNY). The company stated that this adjustment lowers operational costs by about 20% for most agent tasks. Haiku 5.5 scored 1620 on GDPval-AA v2.1 and 1578 on AA-Briefcase v1.1. It also achieved 72.4% on the OSWorld 2.1 offline subset and 39.2% on Terminal-Bench 4.0. Haiku 5.5 is the first Haiku model to support adjustable performance settings, allowing users to choose between cost and intelligence levels. It is also positioned as a sub-agent model for Opus 5.5 and Sonnet 5.5 when executing coding tasks.
